(1)变压器防火措施： (1) transformer fire prevention measures: 1)技术防火措施：①预防变压器绝缘击穿。②预防铁芯多点接地及短路。③预防套管闪络爆炸。④预防引线及分接开关事故。⑤加强油务管理和监督。 1) the technology of fire prevention measures: (1) to prevent transformer insulation breakdown. (2) the prevention of iron core multipoint earthing and short circuit. (3) prevention bushing flashover explosion. (4) prevention and lead tap-changer accident. (5) strengthening the oil service management and supervision. 2)常规防火措施： 2) regular fire prevention measures: ①加强变压器的运行监视。运行中应特别注意引线、套管、油位、油色的检查和油温、音响的监视，发现异常，要认真分析，正确处理。 (1) to strengthen the operation monitoring of transformer. Should pay special attention to in the operation of fuses, casing, oil level, oil color check and monitor the oil temperature, acoustics, found abnormal, want careful analysis, the correct processing. ②保证变压器的保护装置可靠投入。变压器运行时，全套保护装置应能可靠投入，所配保护装置应动作准确无误，保护用直流电源应完好可靠，确保故障时，保护正确动作跳闸，防止事故扩大。 (2) to ensure that the transformer protection device is reliable. Operation of the transformer, a full range of reliable protection device should be able to input, with protective devices shall be accurate, protect with dc power supply should be in good condition and reliable, to ensure that failure, protect right action tripping, prevent accident expanding. ③保持变压器的良好通风。变压器的冷却通风装置应能可靠的投入和保持正常运行，以便保持运行温度不超过规定值。 (3) to keep the good ventilation of the transformer. Transformer cooling ventilation should be able to reliable input and maintain normal operation, in order to keep the operating temperature shall not exceed the specified value. ④设置事故排油坑。室内、室外变压器均应设置事故排油坑，蓄油坑应保持良好状态，蓄油坑有足够厚度和符合要求的卵石层。蓄油坑的排油管道应通畅，应能迅速将油排出，不得将油排入电缆沟。 (4) set up the discharge of oil pit accident. Indoor and outdoor transformer oil discharge hole shall be set up accident, oil storage pit should be kept in good condition, oil storage pit has enough thickness and meet the requirements of pebble bed. Oil storage pit discharge of oil pipeline should be unobstructed, should be able to quickly the oil discharge, may not be the oil into the cable trench.
